Such sealing strips for use in doors and trunk openings of automobiles are known, sometimes in a form in which the crown or apex of the U-shaped sealing strip is provided with a special sealing lip pointing towards the outside and against which a door, trunk lid, or the like rests when closed.

Such sealing strips have, however, the disadvantage that when subjected to large amounts of water and dirt, the seal very often is not tight.

It is, therefore, an object of the present invention to overcome the disadvantages of heretofore known such sealing strips, and in particular, to provide a sealing strip which is fully efiective even under extreme conditions, such as heavy rain fail.

SUMMARY OF THE INVENTION The U-shaped sealing strip provided with a sealing lip at the apex portion of the U-shaped profile to rest against a door, trunk lid or the like, is in accordance with the present invention, characterized primarily in that one leg of the U-shaped sealing strip carries a sealing lip projecting laterally outwardly at an angle and pointing away from the apex and extending beyond a plane passing through the outer edge of this leg of the profile and extending perpendicularly to the plane of symmetry of the sealing strip, and in that this lip upon being mounted on a supporting flange sealingly rests against a member extending from the body of the vehicle at an angle preferably at a right angle with respect to the supporting flange.

In accordance with a further development of the present invention, the sealing strip can be supplemented by a decorative strip having U-shape and being mounted on that leg of the U- shaped sealing strip which is not equipped with the lateral sealing lip so that that leg thereof which is located within the interior space of the sealing strip likewise rests against the supporting flange and contributes to the total sealing effect.

Advantageously, the sealing lips form one unitary structure with the sealing strip.

BRIEF DESCRIPTION OF THE DRAWING The invention will become more readily apparent from the following description of a preferred embodiment thereof shown, by way of example, in the attached drawing, in which:

FIG. 1 illustrates the sealing strip according to the present invention, in a perspective cross sectional view;

FIG. 2 shows the sealing strip of FIG. 1 when mounted on a supporting flange.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT Referring now to the drawings in detail, the U-shaped sealing strip 1 comprises legs 2 and 3 and a metallic insert 4, preferably made of steel. A sealing lip 5 extends from the crown or apex portion of the profile outwardly, in a manner known per se. In operative condition, a door or trunk lid, or the like, 16 rests against this lip (see FIG. 2).

In accordance with the present invention, the leg 2 of the sealing strip carries a further lip 6 which extends laterally at an angle away from the crown or apex portion of the U-shaped profile in such a way that it extends through and beyond a plane defined by the outer edge 7 of the leg 2 and extending perpendicularly to the plane of symmetry of the sealing strip. Upon placement of the sealing strip 1 onto a supporting flange 14 (FIG. 2), lip 7 will rest against a portion 15 of the automobile body or trunk which extends at an angle with respect to the supporting flange 14.

A decorative strip 8 is frequently used with doors or trunk lids of automobiles. This decorative strip 8 oints toward the interior of the automobile, 18 of a U-shape profile, and surrounds leg 3 of the sealing strip in such a way that its portion 9 is located in the interior of the sealing strip 1 and that it rests against the supporting flange 14 upon placement of the sealing strip thereon. Leg 10 of the decorative strip 8 located on the outside is provided with a thin metal insert 11.

In operative position, illustrated in FIG. 2, the lateral sealing lip 6 rests against the portion 15 extending perpendicularly to the supporting flange 14, while the door or trunk lid 16 in closed condition rests against the sealing lip 5. The interior of the car or trunk is to the right of the decorative strip 8. Leg 2 of sealing strip 1 has the interior thereof provided with holding ribs 12 and 13 which tightly rest against the supporting flange 14 in assembled condition, as likewise shown in FIG. 2.

In view of the cooperation of the two sealing lips 5 and 6, one of which sealingly rests against the door, lid or the like, whereas the other rests against a portion of the car body extending substantially perpendicularly from the supporting flange, a complete seal of the interior of the automobile or trunk is obtained, thus preventing penetration of moisture and dirt.

From the above, it is apparent that although the invention has been described hereinbefore with respect to a specific embodiment thereof, it is evident that many modifications and changes may be made without departing from the spirit of the invention. Accordingly, by the appended claims, it is intended to cover all such modifications and changes as fall within the true spirit and scope of this invention.
